How to wire up a consumer unit

Arran Cameron

A semi-detached house has a prehistoric fuse box with rewirable ceramic fuses. It will shortly be replaced with a modern consumer unit. The existing circuits are:



 



1. Lights



2. Upstairs sockets



3. Downstairs sockets



4. Kitchen sockets



5. Cooker



6. Shower



 



The following circuits will be added to the consumer unit:



 



7. Central heating



8. Burglar alarm and CCTV



9. Outside lights



 



I have been informed that the best choice is a split load consumer unit with two RCDs and space for RCBOs. My intention is that circuit 8 has its own RCBO but what is the optimal way to allocate circuits to RCD A and RCD B? Also, should any other circuits have their own RCBO?

    Where has this come from all of a sudden? If it had been in this forum, I am sure that I would have remembered it. ?




    Thinking further, this thread was started a year before the old forum closed and whilst, presumably, most of us were still active over there.


    I thought that the slightly off-topic debate about how whether standards should be openly available was interesting. Whilst I agree that as a general principle, knowledge should be disseminated, BS 7671 is not the sort of book which you can read from cover to cover and suddenly become an electrician. You need to learn how to use it.


    Regarding Asperger's (how's that for thread drift!) we aren't supposed to use the name anymore because he was associated with the Nazi party. Similarly, you might once have had Wegener's granulomatosis, but not any more for the same reason.
